Buyer questions

FAQ for SC(B)18 Three-Phase Dry-Type Power Transformer

What is SC(B)18 Three-Phase Dry-Type Power Transformer best used for?
This model is specified at the required capacity and 10 kV / 20 kV / 35 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for SC(B)18 Three-Phase Dry-Type Power Transformer?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests apply to dry-type transformers?
Dry-type units follow GB 1094.1, GB/T 6451 and IEC 60076-11. Routine tests cover winding resistance, ratio, impedance, no-load and load loss, insulation resistance and power-frequency withstand. Partial-discharge and temperature-rise type tests are available.
Can a dry-type transformer be installed outdoors?
A standard cast-resin unit is intended for indoor, well-ventilated rooms. For outdoor use an IP enclosure, anti-condensation heaters and a corrosion class must be specified. In many coastal or dusty sites an oil-immersed or prefabricated station is a better fit.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
